I had a crack in the foundation of my basement wall and had AquaSeal repair it. They were extremely timely and the service guy was knowledgeable. I was unfamiliar with epoxy injections; however, he took the time to explain the process. He was efficient, professional and courteous. The post-job clean-up was excellent.
Since the crack has been repaired, I have had no issues with it. I would strongly recommend AquaSeal to anyone based on their excellent service and repair. I would use them again. I especially like that their work is under warranty which gives me peace of mind!read more

I called around and talked to 4 other local companies and found that they had the best warranty (25 years transferable) for repairing a water leak in a basement foundation. Pierre was very upfront and knowledgeable answering all my questions when I first contacted them and while repairing the crack in the wall explained the whole process and why it is done. An appointment was made in a timely manner and the job took approx. 2 hours.read more

I had a leak in the foundation wall of my basement. The outside of the wall is under a sun room so a repair from the exterior was not an option. Pierre came and brought his son with him, they both worked hard, diligently and in a timely manner. I could not fault both of their efforts on the day one bit. They located the source of the leak and proceeded with an injection wall treatment until the leak had fully stopped. They cleaned up after themselves and headed off to the next job. I would definitely recommend Aquaseal and wouldn't hesitate to use them again should I ever need to.read more

PaulT in New Castle Ontario. I had a crack in my basement wall and I tried fixing it with Hydraulic cement. Unfortunately, I had no luck and was just wasting my time. I called Aquaseal and they were there in 3 hours and the problem was fixed in a couple of hours with epoxy. They were very professional and left the basement neat and tidy. They were careful to explain how to deal with the Epoxy odours which mostly went away in about 5 hours. I should have called them first and I thought the price was reasonable.read more

The service men explained the process well, worked very efficiently and cleaned up well. The life time guarantee sold me, since my neighbour had work done and their process failed. I have had 4 years of dry while my sump pump runs when the ground get wet. Will call them back if necessary.read more

I was in the middle of a home inspection when I called Aquaseal at the recommendation of my real estate agent. The home inspector found a crack in the foundation and recommended we call an expert. Pierre came to the house within 30 minutes. He immediately put my mind at ease and confirmed it was not structural and could be fixed by him and his team. He continued to inspect the rest of the foundation and offered to fix another issue- both would come with a 25-year warranty.
Pierre was professional, accurate and a really great guy. He has over 20 years’ experience and I totally trust his expertise. I have already recommended him to my brother and my parents. Thanks to Pierre and Aquaseal!read more
